在 MetroCluster 配置中移动元数据卷
可以将元数据卷从 MetroCluster 配置中的一个聚合移动到另一个聚合。您可能希望在源聚合已停用或取消镜像的情况下移动元数据卷,或者出于其他导致聚合不合格的原因进行此操作。
开始之前
必须具有集群管理员权限才能执行此任务。
目标聚合必须是镜像聚合,不应处于降级状态。
目标聚合中的可用空间必须大于要移动的元数据卷。
- 将权限级别设置为高级:set -privilege advanced
- 确定应移动的元数据卷:volume show MDV_CRS*
示例
Cluster_A::*> volume show MDV_CRS*

示例
以下命令将确定 cluster_A 中可以托管元数据卷的聚合:
Cluster_A::*> metrocluster check config-replication show-aggregate-eligibility
